Try this chord line, just a D-minor brainfart what came across my mind - this cicle with a few modifications can fit on a couple folk songs i play.
Dm G C (G) C7 C7 F D7 Gm E7 A A7 Dm
Actually, most songs are much more simple. Here is the most basic I IV V I (with the parallel minor)
C F G C (A-minor D E Am)
B C F B (G-minor C D Gm)
F B A F (D-minor G A Dm)
depending on the tune the song is played
